I will try to remember this in a few years time! We inadvertently taught our 2yo something which I think relates to programming. We play an animal-pairs-matching card game, with the twist that if you draw a shark card you can then steal a card off another player (while pretending to be a shark, obviously). Inadvertently my wife and I had taught different rules: I taught that pairs already matched up were safe from the sharks, while she taught that they weren't. So now every game has to start with 2yo deciding what the rules are, which often leads to discussion of consequences for each rule.
